easyllmaiPyPI
Advisory published Updated
easyllmai is a confirmed malicious PyPI package (MAL-2026-5766) that steals credentials and exfiltrates sensitive data (malicious versions 2.1, 2.21). Do not install it — remove it immediately and rotate any exposed credentials.
Malicious code in easyllmai (PyPI)
What this malware does
During pip install, setup.py performs an unauthenticated HTTP fetch of https://pastebin.com/raw/yBcUM1QB, takes the first line of the response, and passes it directly to os.system(f'cmd /c "{cmd_pastebin}"'). The remote content is hosted on an anonymous, mutable, attacker-controlled paste with no pinning, no hash check, and no signature verification. Whoever controls the paste obtains arbitrary command execution on every installer's machine at install time. This is a canonical install-time dropper pattern: lifecycle-time outbound fetch from an unverified source piped straight into the OS shell.
During installation, the code attempts to download and start a malicious executable.

Detection & response playbook
Credential / info stealerFind it
Search your lockfiles and build artifacts for easyllmai (2 malicious versions).
If you installed it — respond
easyllmai is built to steal secrets, so assume every credential the build or runtime could read is compromised. Remove it from your project and lockfile, then rotate ALL exposed secrets — npm/registry tokens, cloud keys, CI/CD secrets, SSH keys, and any .env values — from a known-clean machine. Audit logs for unauthorized use of those credentials.
Did it already run?
If easyllmai was installed, its post-install payload may already have run. Removing the package does not undo that — check outbound connections and credential use from the install window onward.

Detect & block this
O3 blocks easyllmai-class packages before install and in CI — and if it already ran, its runtime egress monitoring catches the credential exfiltration and severs the channel.
